Workshop on using the Magnolia HPC cluster.

When:  July 18, 2023 10 am — 12 pm
Where:  PSRC 105
Registration:   Register here.


Description

This workshop is intended for users that have used the cluster and wish to learn how to use it more efficiently. and for High Performance Computing (HPC). Below is a list of topics which will be covered. Each topic covered will be an overview, enough so that the users know the options exist, and where to get detailed information if they are found useful.

Topics in this workshop:

  • Introduction to the Magnolia High Performance Computing (HPC) cluster
  • HPC workflow
  • Quick review of Linux shell commands
  • Using pre-installed programs and software (Linux Environment Modules)
  • Python
  • Compiling C/C++ programs
  • How serial (single threaded) programs can take advantage of HPC Clusters

Prior knowledge of the Magnolia HPC cluster will be useful, but not required. If you have not yet used the cluster, please check that you can connect by following the instructions in the Check connection to the cluster section below.

Requirements

Bring a laptop that can connect to the Magnolia HPC Cluster (see the Check connection to the cluster section below).

Registration

Please fill out the registration form to reserve a seat.

Direct link to the registration form: https://redcap.usm.edu/surveys/?s=33D4LKAWY8NLX9X3

Check connection to the cluster

Connecting to the cluster is typically done using ssh (see Connecting/Login for more details). If you are using Linux or OSX, ssh is used from the terminal. Type the command shown below to check the host key fingerprint. Do not enter any passwords. Instead, cancel by typing Control+C. For Windows users, install an {{C|ssh} client like PuTTY (http://www.putty.org) and follow the directions given in the following link: Windows Specific Directions

user $ssh -o VisualHostKey=yes check@magnolia.usm.edu
Host key fingerprint is SHA256:glQIZZKlsAwf3QJNNDQSxFpRzE2rKs4GfxByO6ZBzis

check@magnolia.usm.edu's password:

Make sure that the host key fingerprint (In this case: SHA256:glQIZZKlsAwf3QJNNDQSxFpRzE2rKs4GfxByO6ZBzis) matches one of the fingerprints given in the list of SSH fingerprints for Magnolia. SSH_Fingerprints/magnolia.usm.edu
